After Betty gets an embarrassing haircut from her mom, she gets called on a mission to stop Maximus from stealing the galaxy's gold resources to build a golden statue of himself. Although another Galactic Guardian, Atomic Roger, keeps arriving and saving the day before she can and stealing all the glory. Will Betty get upstaged from having the title of the Galaxy's most notable Galactic Guardian to Atomic Roger? (Villains: Maximus IQ, Atomic Roger)

Betty and the crew have an important mission—towing the incredibly large Querzanian Diamond across a dangerous galaxy to avoid galactic warfare—but Sparky has gone on a cruise for vacation. He soon finds out that the so-called "cruise-ship" is actually Greenbeard's pirate ship! Greenbeard claims to have "gone straight", but once Sparky tells him about the diamond, he is determined to have it. On Earth, Betty has found a model replica of her spaceship at a yard sale that she really enjoys, but can't afford the money to buy it.

• The title is a pun on "buried treasure." (Villain: Greenbeard)

Atomic Betty leaves a hectic Christmas on Earth to rescue a constellation of nine planets known as the No-L 9 from being shrunk down to tree ornament size by the evil Maximus I.Q. (Villains: Maximus I.Q., Infantor)

Betty has been invited to Noah's place, where he's about to demonstrate to her a satellite radio (that inadvertently eavesdrops on Admiral DeGill's personal activities). Leaving, she sees Paloma being chased by Duncan as a result of a prank. Before Duncan can catch either of them, a spaceship appears out of nowhere and abducts Paloma, to Betty's horror. Beaming aboard her ship, she discovers that Sparky and X-5 are being held hostage by Paloma's younger sister, Juanita. Demanding an explanation, Juanita explains that she is, in fact, a Galactic Guardian who is responsible for Paloma's safety. Betty and her crew are forced to accept help from Juanita to save Paloma.

Paloma is, in fact, one of the twin daughters of Golgotha, whose people have the ability to shapeshift into any living thing. However, Golgotha became power-hungry, and unleashed a demon who couldn't be transformed into on her own people; the demon is, in fact, Paloma's father. Without the ability to transform into the demon, Golgotha terrorized her own people, until the couple was ultimately defeated by the best warriors from the other planets. These warriors, in turn, banded together to form the first generation of Galactic Guardians. Since then, the demon had been sealed within a box under Spindly Tam Kanushu's care, and the key to unlocking the box was hidden in a ceramic duck that Maximus had recently acquired. For some time, Paloma's twin sister, Pandora, has tried to secure both of these items, and on one occasion Paloma was the cause of her defeat. Since then, Paloma had been placed in a witness protection program, and assumed a normal life on Earth; Juanita had incorrectly assumed that the presence of Betty would allow her to loosen her guard; however, Betty had never learned of Paloma's secret.

Meanwhile, Pandora has managed to secure both of the artifacts needed to resurrect her father, defeating both Spindly Tam and Maximus, and Admiral DeGill, and has captured Paloma as one of her sacrifices. Betty is forced to team up with a freed Maximus (intending to recover the stolen duck) to mount an attack on Pandora's base. However, it's too late: the demon has resurrected. The combined force of the guardians and Maximus is unable to defeat the demon, but Paloma, from within captivity, can free herself, and seal her father and her twin sister in the box, using the good powers that she had inherited from her father. The box is returned to Spindly Tam's temple, while the key somehow finds its way into Noah's possession, overloading the satellite radio and teleporting him into Maximus' citadel. The episode ends on a cliffhanger as Maximus returns to his own citadel, with Noah in his personal quarters. (Villains: Pandora and Beluvian Demon)

• Note: This episode was dedicated to Len Carlson's memory who died of a heart attack on January 26, 2006 at the age of 68.

Previously, Pandora and her father had been re-imprisoned. However, the reimprisonment had also managed to teleport Noah into Maximus' base. When Betty hears of Noah's apparent capture, Betty goes to save him while Paloma tries to defuse the mass hysteria that has hit Moose Jaw. Meanwhile, while Minimus keeps Noah company as a playmate, Maximus employs the Chameleon to disguise himself as Noah, who is subsequently "rescued" by Betty. Returning to Galactic Guardian headquarters, Betty remarks that Noah would make a great Galactic Guardian, just as Maximus arrives with his armada. Noah inadvertently destroys Galactic Guardian headquarters when a superball he and Minimus were playing with activates Maximus' weapon.

With Galactic Guardian headquarters destroyed, Admiral DeGill decides to build a temporary headquarters on Earth, underneath Moose Jaw, much to the chagrin of Betty. While Paloma and Juanita help build the base, and Sparky and X-5 adjust to Betty's civilian life, Betty discovers the Chameleon's ruse after discovering that "Noah" is afraid of Purrsy and appears to not know the way back to his own house from hers. Paloma rescues Noah after disguising herself as the Chameleon and sneaking aboard Maximus' ship but is forced to say one last goodbye to Betty to get Maximus away from Earth and prevent its destruction. After the ordeal, Betty keeps her word and allows Noah to join the Galactic Guardians as a cadet. Note 1: Final main character appearance of Paloma and Juanita.

Note 2: It also marks the final time the Chameleon appears as a major villain.

Note 3: This is the first time since Bracelet Yourself that Sparky dons his Earth disguise.

While battling a group of blood monks on Morbidia, Sparky ingests a bowl of Buhdonkian pig snouts (his favorite snack), unaware that it contains a microchip that allows Maximus to remotely mind control Sparky; Maximus intends to use the mind-controlled Sparky to kill Betty. Meanwhile, Betty is nervous over a skateboarding stunt she has to do to kick off a town festival. X-5 assures her that her stunt, where she must do a series of hard tricks before setting off a series of fireworks in the air with a torch in her hand, will succeed; to ensure its success X-5 provides her with a magnetic glove (intended to keep the torch on her hand). That night, Maximus' plan is put into action, as he takes control of Sparky and has him take a restricted weapon. X-5, enjoying the festival from a distance, notices Sparky, and alerts Betty to the attempt on her life; Betty subsequently, while in the middle of the stunt, throws the glove at Sparky, knocking him out and destroying the microchips. Betty would complete her stunt without the assistance of the magnetic glove, while Sparky, recovering from a stomachache caused by the glove hitting him, accidentally discharges the weapon, sending rounds into the air which knock out Maximus' citadel, and adding to the fireworks show.

It's Betty's thirteenth birthday, and Betty's family and friends are arranging a surprise birthday party. Meanwhile, after years of work, X-5 has managed to complete a working time machine. As a sign of the accomplishment, Admiral DeGill is ordered to present the time machine at the Galactic Council. However, this is a trap set by Maximus, who captures the time machine and travels into the future, with Sparky, X-5, Beatrixo, and Admiral DeGill as hostages. A downcast Betty and Noah, both having eluded capture, returns to Betty's birthday party, where a hand-me-down "re-gift" from Penelope inspires her to repair a prototype time machine (its only flaw being that it turned its occupants into gelatin) to full working order and travel to the future.

Betty and Noah arrive in the year 2013 to find a dystopic Moose Jaw Heights. Maximus has taken control of Earth, and the Galactic Guardians have been reduced to a small pocket of resistance, consisting of the seventeen-year-old Atomic Betty as well as teenage future versions of Noah, Chaz, Regeena, and even Penelope; all who know of Betty having been a dutiful and strong Galactic Guardian for several years.

After the prototype time machine is destroyed, the Galactic Guardians of the present and future launch an attack against Maximus in his Earth stronghold on Beatrixo's farm in a bid to capture the original time machine, which results in their own capture. After gloating that the four present-day hostages are scattered around the universe, the present Betty manages to trick Maximus into "repairing" his time machine (ostensibly to prevent motion sickness by its occupants), before a timely distraction by the future Penelope allows Betty and Noah to take the time machine themselves and travel back to the past.

Back in the present, Betty convinces X-5 to present the flawed prototype instead of the working model, and the others of Maximus' impending trap. The better-equipped Galactic Guardians manage to drive off Maximus, but Maximus manages to capture the prototype time machine. When he tries to use it, it predictably fails, turning him and Minimus into green gelatin. Meanwhile, Betty, Noah, and Beatrixo return to the birthday party, where their secret is accidentally leaked to Penelope (on a note written by the future teenage Penelope planted on Noah's clothing), who simply believes the galactic secret to be a fabrication and thinks that Betty is always nothing but a loser. After Penelope leaves, Betty is relieved and calls her teenage future self, wishing her a happy birthday and thanking her for everything. Future teenage Atomic Betty also wishes Betty a happy birthday and hopes to talk to her soon. After the call, Betty is then joined by her friends and family, all of whom share a laugh.
